Ultrasound-guided cortisone injections may be an effective treatment for gluteus medius tendinopathy, a painful condition caused by an injury to the tendons in the buttocks of elderly women. Medical treatment of the condition typically includes physiotherapy, nonsteroidal anti-inflammatory drugs (NSAIDs), and corticosteroid injections. The study included 54 patients with gluteus medius tendinopathy. Ultrasound-guided corticosteroid injections were performed on all patients. One month after treatment, 72 percent of the patients showed a significant improvement in pain level. The advantages of ultrasound over fluoroscopy (X-ray), said the studys authors, include its soft-tissue imaging capabilities, which allow a diagnostic study to be performed before the injection of corticosteroids.
